Product Summary

The Quad ISDN High Voltage Power Controller PEF2426 provides a power source for up to four U-line interfaces. The power source to PEF2426 is a local battery or a centralized power supply. Each powered line is individually controlled and monitored by the device interface. Line powering can be switched on or off by command. The QIHPC indicates, when the output current is above a threshold for longer than the programmable time tOC.

Parametrics

PEF2426 absolute maximum ratings: (1)Operating ambient temperature range, PEB,TA: 0 to 70℃; (2)Operating ambient temperature range, PEF, TA: -40 to 85℃; (3)Storage temperature range, Tstg: -65 to 125℃; (4)Voltage on pin VDD with respect to ground, VDDmax: -0.4 to +8V; (5)Voltage on pin VILF with respect to ground VILFmax: -140 to VDD+0.4V; (6)Voltages on pins D1..4 with respect to VILF, VD1..4max: -0.4 to +150V.

Features

PEF2426 features: (1)ISDN Line Feed Supply Voltage up to 130 V; (2)Supplies power for up to four ISDN transmission lines; (3)ETSI TS 102 080 compatible; (4)Separate Current Monitoring and Limiting for each line; (5)Current Limiting Level can be programmed by an external resistor; (6)Overcurrent indication threshold can be programmed with external resistors; (7)independently from the current limitation.; (8)The overcurrent indication setup delay can be programmed by external capacitors, separately for each line; (9)Intelligent Chip Temperature Control; (10)Automatically switching off lines in current limitation when expecting over temperature problems; (11)Automatically switching off all four lines in case of real overtemperature; (12)Integrated Relay Drivers and Relay Driver Controlling for eight relays; (13)Optimized for working in conjunction with PEB 24901 (DFE-T), PEB 24911 (DFE-Q), and PEB 2491 (QUAD-U); (14)Small P-MQFP-44 Package; (15)Reliable 170 V Smart Power Technology.
